Description

Technical Field

[0001] This invention relates to the field of power substation technology, and more specifically to a protective device and method for a portable power supply for energy storage. Background Technology

[0002] A storage battery is a device that directly converts chemical energy into electrical energy. It is designed to be rechargeable, achieving recharging through a reversible chemical reaction. It typically refers to lead-acid batteries, a type of secondary battery. Its working principle is as follows: during charging, external electrical energy is used to regenerate the internal active materials, storing electrical energy as chemical energy. When discharging is needed, the chemical energy is converted back into electrical energy for output, such as in commonly used mobile phone batteries.

[0003] In the prior art, such as the portable household energy storage power device disclosed in Chinese Patent No. CN114944687A, the device includes a placement box with symmetrical placement clearance grooves in the middle of its side wall; a moving component disposed at the bottom of the placement box; two sets of shielding covers symmetrically slidably disposed on the top of the side wall of the placement box; an elastic reset component disposed between the outer side wall of the placement box and the shielding covers for automatic reset and closure after the symmetrically disposed shielding covers are opened; and a placement positioning component disposed between the outer side wall of the placement box and the shielding covers for positioning after the shielding covers are opened. Thus, with the cooperation of the moving component, the energy storage power can be conveniently carried, avoiding excessive manpower consumption and solving the problem of existing energy storage power supplies being inconvenient to carry and requiring manpower. Simultaneously, it can protect the energy storage power during transport to prevent damage caused by movement.

[0004] However, while the aforementioned patents have the above-mentioned technical advantages, their disadvantages are that the equipment can only be used with large-volume batteries. For outdoor workers, small-volume portable batteries cannot be matched with the aforementioned equipment. Furthermore, due to the harsh external environment during outdoor operations, the traditional exposed batteries have poor external protection and are easily damaged during the continuous movement and climbing of personnel. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the technical solution adopted by this invention is as follows: a protective device for a portable power supply for energy storage, comprising a waist belt, a fixing plate fixedly connected to the outer surface of the waist belt, a spring piece fixedly connected to the outer surface of the fixing plate, a clamping plate fixedly connected to the outer surface of the spring piece, a rubber strip provided on the right side of the clamping plate, a movable block provided on the right side of the rubber strip, a diagonal strap fixedly connected to the upper surface of the movable block, a shoulder pad fixedly connected to the outer surface of the diagonal strap, and an isolation device fixedly connected to the outer surface of the movable block. When the waist belt is worn around the waist, as the waist belt tightens, the clamping plate contacts and presses against the waist, the spring piece abuts against the fixing plate, and the rubber strip contacts and presses against the other side of the waist, causing the rubber strip to bend.

[0006] The isolation device includes a housing with a turntable on its exterior. A screw is fixedly connected to the outer surface of the turntable, and a pressure plate is threadedly connected to the outer surface of the screw. A side plate is provided on the top of the pressure plate, and a base plate is provided at the bottom of the side plate. A compression spring is fixedly connected to the lower surface of the base plate, and a capacitor is provided at the bottom of the compression spring. Insulating ceramics are fixedly connected to both ends of the capacitor. The shoulder pad is tightened diagonally by a diagonal strap, providing a diagonal pulling force to the isolation device, distributing the pressure of the battery to the shoulders, and further reducing the pressure on the waist. This waist-mounted portable power supply can fully free the wearer's hands.

[0007] In a preferred embodiment, the inner surface of the movable block is slidably connected to the outer surface of the belt, the inner surface of the belt is fixedly connected to both ends of the rubber strip, the lower surface of the fixing plate is fixedly connected to the outer surface of the clamping plate, and the outer surface of the movable block is fixedly connected to the outer surface of the outer shell. Under the bidirectional clamping and fixing of the clamping plate and the rubber strip, the belt can be effectively prevented from falling off. At the same time, the belt does not require excessive clamping force, which can reduce the pressure on the waist. The isolation device outside the movable block is equipped with a storage battery.

[0008] In a preferred embodiment, the inner surface of the housing is rotatably connected to the outer surface of the screw, the inner surface of the housing is slidably connected to the outer surface of the base plate, the bottom end of the compression spring is fixedly connected to the inner surface of the housing, the lower surface of the housing is fixedly connected to the upper surface of the insulating ceramic, the housing is placed on one side of the waist, the battery enters the housing from the top of the housing, and then the screw is rotated by rotating the turntable, the pressure plates move closer to each other, and the front and rear of the battery are clamped and fixed.

[0009] In a preferred embodiment, a hollow shell is fixedly connected to the outer surface of the outer casing, and reinforcing ribs are fixedly connected to the outer surface of the hollow shell. The reinforcing ribs are linearly arranged along the outer surface of the hollow shell. During the fall of the battery, the lower surface of the battery contacts and presses against the upper surface of the base plate, and the compression spring compresses and contracts. The outer surface of the toothed disc at the top of the base plate rolls into contact with the inner surface of the outer casing. The rotating toothed disc drives the arc-shaped plate to rotate and approach the base plate through the rotating shaft. The rotating arc-shaped plate presses against both sides of the battery to prevent the battery from swaying and impacting from side to side. By fixing the battery, the fixing effect is increased.

[0010] In a preferred embodiment, a piston is fixedly connected to the lower surface of the base plate, a sealing cover is slidably connected to the outer surface of the piston, a connecting pipe is fixedly connected to the inner surface of the sealing cover, and a cavity is provided outside the connecting pipe. When the base plate is pressed down, the piston retracts into the interior of the sealing cover, and the hydraulic oil inside the sealing cover is injected into the interior of the cavity through the connecting pipe. The hydraulic oil level inside the cavity rises, and the baffle is forced to rise under the push of the hydraulic oil.

[0011] In a preferred embodiment, a rotating shaft is rotatably connected to the outer surface of the top of the base plate, and a gear plate is fixedly connected to the outer surface of the rotating shaft. An arc-shaped plate is provided on the outside of the gear plate. The bottom of the inclined side plate is pushed upward by the connecting rod, and the pin at the top of the side plate is forced to slide horizontally along the inside of the slide groove. The inclined side plate gradually becomes horizontal, and the two side plates move closer to each other, so that the top of the housing is closed and the battery is sealed inside the housing.

[0012] In a preferred embodiment, a baffle is slidably connected to the inner surface of the cavity, and a connecting rod is fixedly connected to the upper surface of the baffle. The outer surface of the top of the connecting rod is rotatably connected to the lower surface of the side plate. The hollow shell and the outer shell are in contact with the outside world. The reinforcing ribs increase the structural strength of the hollow shell. The hollow shell can not only buffer external impacts, but also increase the buoyancy of the device through the air inside the hollow shell after the isolation device falls into the water, thus preventing the battery from sinking.

[0013] In a preferred embodiment, a groove is formed in the wall of the outer casing, and a pin is slidably connected to the inner surface of the groove. The outer surface of the pin is fixedly connected to the upper surface of the side plate. The groove is horizontally opened, and the existence of the cavity forces the outer casing to form a hollow double-layer structure. When the outer layer of the outer casing breaks, there is an inner layer for secondary buffering. Furthermore, when the side plate is closed, hydraulic oil is filled between the inner and outer layers, which can effectively reduce the direct impact of the external ambient temperature on the battery. Metal wires are installed inside the insulating ceramic.

[0014] In a preferred embodiment, the cavity is formed in the wall of the outer shell, the lower surface of the outer shell is fixedly connected to the lower surface of the sealing cover, the inner surface of the arc plate is fixedly connected to the outer surface of the rotating shaft, and the arc plate is linearly arranged along the outer surface of the rotating shaft. When the battery leaks current, the wire conducts the current to the inside of the capacitor, and the capacitor is charged.

[0015] A method of using a protective device for a portable power supply for energy storage includes the following steps:

[0016] Step 1: Secure the belt around your waist and adjust its length to prevent it from slipping off;

[0017] Step 2: Wear the shoulder strap diagonally and adjust its length so that the shoulder pads are angled against your shoulders;

[0018] Step 3: Insert the battery into the isolation device. As the battery falls, it will automatically clamp and fix itself in place by its own weight.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. This invention features a waist belt. When the device is in use, the waist belt is worn around the waist. As the waist belt tightens, the clamping plate contacts and presses against the waist, the spring clip abuts against the fixing plate, and the rubber strip contacts and presses against the other side of the waist. The rubber strip bends, and the opposing clamping and fixing of the clamping plate and the rubber strip effectively prevents the waist belt from falling off. At the same time, the waist belt does not require excessive clamping force, which reduces pressure on the waist. The isolation device on the outside of the moving block has a battery installed inside. The shoulder pad is tightened diagonally by the diagonal strap, giving the isolation device a diagonal pulling force, distributing the pressure of the battery to the shoulders, further reducing pressure on the waist. The waist-mounted portable power supply can fully free the wearer's hands.

[0021] 2. This invention incorporates an isolation device. When the device is in use, the outer casing is placed on one side of the waist area, and the battery enters the casing from the top. A rotating turntable then drives a screw to rotate, causing pressure plates to move closer together. The front and rear of the battery are clamped and fixed. As the battery falls, its lower surface contacts and presses against the upper surface of the base plate, compressing the spring. The outer surface of the toothed disc at the top of the base plate rolls against the inner surface of the outer casing. The rotating toothed disc, via a shaft, drives an arc-shaped plate to rotate and approach the base plate. The rotating arc-shaped plate presses against both sides of the battery, preventing it from swaying and impacting. By fixing the battery, the fixing effect is enhanced.

[0022] 3. This invention uses a piston. When the equipment is in use, the base plate is pressed down, and the piston retracts into the interior of the sealing cover. The hydraulic oil inside the sealing cover is injected into the cavity through the connecting pipe. The hydraulic oil level inside the cavity rises, and under the push of the hydraulic oil, the baffle is forced to rise. The bottom of the inclined side plate is pushed upward by the connecting rod, and the pin at the top of the side plate is forced to slide horizontally along the inside of the slide groove. The inclined side plate gradually becomes horizontal, and the two side plates move closer to each other, so that the top of the casing is closed and the battery is sealed inside the casing.

[0023] 4. This invention incorporates a cavity. When the device is in use, the hollow shell and outer shell are in contact with the outside environment. The reinforcing ribs increase the structural strength of the hollow shell. The hollow shell not only buffers external impacts but also increases the buoyancy of the device by the air inside the hollow shell after the isolation device falls into water, preventing the battery from sinking. The presence of the cavity forces the outer shell to form a hollow double-layer structure. When the outer layer of the outer shell breaks, there is an inner layer for secondary buffering. Furthermore, when the side panel is closed, hydraulic oil is filled between the inner and outer layers, which can effectively reduce the direct impact of the external ambient temperature on the battery. Metal wires are installed inside the insulating ceramic. When the battery leaks current, the wires conduct the current to the inside of the capacitor, charging the capacitor.

[0034] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0035] Example 1:

[0036] Please see Figure 1 - Figure 9 The present invention provides a technical solution: a protective device for a portable power supply for energy storage, including a waist belt 1, a fixing plate 2 fixedly connected to the outer surface of the waist belt 1, a spring piece 3 fixedly connected to the outer surface of the fixing plate 2, a clamping plate 4 fixedly connected to the outer surface of the spring piece 3, a rubber strip 5 provided on the right side of the clamping plate 4, a moving block 6 provided on the right side of the rubber strip 5, a diagonal strap 7 fixedly connected to the upper surface of the moving block 6, a shoulder pad 8 fixedly connected to the outer surface of the diagonal strap 7, and an isolation device 9 fixedly connected to the outer surface of the moving block 6; the isolation device 9 includes a housing 10, a turntable 11 provided on the outside of the housing 10, a screw 12 fixedly connected to the outer surface of the turntable 11, a pressure plate 13 threadedly connected to the outer surface of the screw 12, a side plate 14 provided on the top of the pressure plate 13, a bottom plate 15 provided on the bottom of the side plate 14, a compression spring 16 fixedly connected to the lower surface of the bottom plate 15, a capacitor 17 provided at the bottom of the compression spring 16, and insulating ceramics 18 fixedly connected to both ends of the capacitor 17. The inner surface of the movable block 6 is slidably connected to the outer surface of the waist belt 1, the inner surface of the waist belt 1 is fixedly connected to both ends of the rubber strip 5, the lower surface of the fixing plate 2 is fixedly connected to the outer surface of the clamping plate 4, and the outer surface of the movable block 6 is fixedly connected to the outer surface of the outer shell 10.

[0037] The waist belt 1 is worn around the waist. As the waist belt 1 tightens, the clamp 4 contacts and presses against the waist. The spring 3 abuts against the fixing plate 2, and the rubber strip 5 contacts and presses against the other side of the waist. The rubber strip 5 bends. Under the opposing clamping and fixing of the clamp 4 and the rubber strip 5, the waist belt 1 can be effectively prevented from falling off. At the same time, the waist belt 1 does not require excessive clamping force, which can reduce the pressure on the waist. The isolation device 9 outside the moving block 6 has a battery installed inside. The shoulder pad 8 is tightened diagonally by the diagonal strap 7, which gives the isolation device 9 a diagonal pulling force, distributing the pressure of the battery to the shoulder and further reducing the pressure on the waist. The waist-mounted portable power supply can fully free the wearer's hands.

[0038] The inner surface of the outer casing 10 is rotatably connected to the outer surface of the screw 12, and the inner surface of the outer casing 10 is slidably connected to the outer surface of the base plate 15. The bottom end of the compression spring 16 is fixedly connected to the inner surface of the outer casing 10, and the lower surface of the outer casing 10 is fixedly connected to the upper surface of the insulating ceramic 18. A hollow shell 19 is fixedly connected to the outer surface of the outer casing 10, and reinforcing ribs 20 are fixedly connected to the outer surface of the hollow shell 19. The reinforcing ribs 20 are linearly arranged along the outer surface of the hollow shell 19.

[0039] The outer casing 10 is placed on one side of the waist. The battery enters the interior of the outer casing 10 from the top. Then, by rotating the turntable 11, the screw 12 is rotated, and the pressure plates 13 move closer to each other, clamping and fixing the front and back of the battery. During the fall of the battery, the lower surface of the battery contacts and presses against the upper surface of the base plate 15, and the compression spring 16 is compressed and contracted. The outer surface of the toothed disc 26 on the top of the base plate 15 rolls and contacts the inner surface of the outer casing 10. The rotating toothed disc 26 drives the arc plate 27 to rotate and move closer to the base plate 15 through the rotating shaft 25. The rotating arc plate 27 presses against both sides of the battery to prevent the battery from swaying and impacting from side to side. By fixing the battery, the fixing effect is increased.

[0040] A piston 21 is fixedly connected to the lower surface of the base plate 15. A sealing cover 22 is slidably connected to the outer surface of the piston 21. A connecting pipe 23 is fixedly connected to the inner surface of the sealing cover 22. A cavity 24 is provided outside the connecting pipe 23. A rotating shaft 25 is rotatably connected to the outer surface of the top of the base plate 15. A gear disk 26 is fixedly connected to the outer surface of the rotating shaft 25. An arc-shaped plate 27 is provided outside the gear disk 26.

[0041] The base plate 15 is pressed down, and the piston 21 retracts into the interior of the sealing cover 22. The hydraulic oil inside the sealing cover 22 is injected into the interior of the cavity 24 through the connecting pipe 23. The hydraulic oil level inside the cavity 24 rises. Under the push of the hydraulic oil, the baffle 29 is forced to rise. The bottom of the inclined side plate 14 is pushed upward by the connecting rod 28. The pin 31 at the top of the side plate 14 is forced to slide horizontally along the interior of the slide groove 30. The inclined side plate 14 gradually becomes horizontal, and the two side plates 14 move closer to each other, so that the top of the housing 10 is closed and the battery is sealed inside the housing 10.

[0042] A baffle 29 is slidably connected to the inner surface of cavity 24, and a connecting rod 28 is fixedly connected to the upper surface of baffle 29. The outer surface of the top of the connecting rod 28 is rotatably connected to the lower surface of side plate 14. A groove 30 is formed in the wall of outer shell 10, and a pin 31 is slidably connected to the inner surface of groove 30. The outer surface of pin 31 is fixedly connected to the upper surface of side plate 14. The groove 30 is horizontally formed. Cavity 24 is formed in the wall of outer shell 10. The lower surface of outer shell 10 is fixedly connected to the lower surface of sealing cover 22. The inner surface of arc plate 27 is fixedly connected to the outer surface of rotating shaft 25. Arc plate 27 is linearly arranged along the outer surface of rotating shaft 25.

[0043] Hollow shell 19 and outer shell 10 are in contact with the outside world. Reinforcing ribs 20 increase the structural strength of hollow shell 19. Hollow shell 19 can not only buffer external impacts, but also increase the buoyancy of the equipment through the air inside hollow shell 19 after the isolation device 9 falls into the water, preventing the battery from sinking. The existence of cavity 24 forces outer shell 10 to form a hollow double-layer structure. When the outer layer of outer shell 10 breaks, there is an inner layer for secondary buffering. Furthermore, when side plate 14 is closed, hydraulic oil is filled between the inner and outer layers, which can effectively reduce the direct impact of external ambient temperature on the battery. Metal wires are installed inside insulating ceramic 18. When the battery leaks, the wires conduct the current to the inside of capacitor 17, and capacitor 17 is charged.

[0044] A method of using a protective device for a portable power supply for energy storage, employing the protective device for a portable power supply for energy storage according to any one of claims 1-9, includes the following steps:

[0045] Step 1: Secure the belt 1 around your waist and adjust its length to prevent it from slipping off;

[0046] Step 2: Wear the shoulder strap 7 diagonally and adjust its length so that the shoulder pad 8 rests diagonally against the shoulder.

[0047] Step 3: Insert the battery into the isolation device 9. As the battery falls, it is automatically clamped and fixed by its own weight.

[0048] Working principle:

[0049] When the device is in use, the waist belt 1 is worn around the waist. As the waist belt 1 tightens, the clamp 4 contacts and presses against the waist, the spring 3 abuts against the fixing plate 2, and the rubber strip 5 contacts and presses against the other side of the waist. The rubber strip 5 bends, and under the opposing clamping and fixing of the clamp 4 and the rubber strip 5, the waist belt 1 can be effectively prevented from falling off. At the same time, the waist belt 1 does not require excessive clamping force, which can reduce the pressure on the waist. The isolation device 9 outside the moving block 6 has a battery installed inside. The shoulder pad 8 is tightened diagonally by the diagonal strap 7, which gives the isolation device 9 a diagonal pulling force, distributing the pressure of the battery to the shoulder and further reducing the pressure on the waist. The waist-mounted portable power supply can fully free the wearer's hands.

[0050] The outer casing 10 is placed on one side of the waist. The battery enters the interior of the outer casing 10 from the top. Then, by rotating the turntable 11, the screw 12 is rotated, and the pressure plates 13 move closer to each other, clamping and fixing the front and back of the battery. During the fall of the battery, the lower surface of the battery contacts and presses against the upper surface of the base plate 15, and the compression spring 16 is compressed and contracted. The outer surface of the toothed disc 26 on the top of the base plate 15 rolls and contacts the inner surface of the outer casing 10. The rotating toothed disc 26 drives the arc plate 27 to rotate and move closer to the base plate 15 through the rotating shaft 25. The rotating arc plate 27 presses against both sides of the battery to prevent the battery from swaying and impacting from side to side. By fixing the battery, the fixing effect is increased.

[0051] The base plate 15 is pressed down, and the piston 21 retracts into the interior of the sealing cover 22. The hydraulic oil inside the sealing cover 22 is injected into the interior of the cavity 24 through the connecting pipe 23. The hydraulic oil level inside the cavity 24 rises. Under the push of the hydraulic oil, the baffle 29 is forced to rise. The bottom of the inclined side plate 14 is pushed upward by the connecting rod 28. The pin 31 at the top of the side plate 14 is forced to slide horizontally along the interior of the slide groove 30. The inclined side plate 14 gradually becomes horizontal, and the two side plates 14 move closer to each other, so that the top of the housing 10 is closed and the battery is sealed inside the housing 10.

[0052] Hollow shell 19 and outer shell 10 are in contact with the outside world. Reinforcing ribs 20 increase the structural strength of hollow shell 19. Hollow shell 19 can not only buffer external impacts, but also increase the buoyancy of the equipment through the air inside hollow shell 19 after the isolation device 9 falls into the water, preventing the battery from sinking. The existence of cavity 24 forces outer shell 10 to form a hollow double-layer structure. When the outer layer of outer shell 10 breaks, there is an inner layer for secondary buffering. Furthermore, when side plate 14 is closed, hydraulic oil is filled between the inner and outer layers, which can effectively reduce the direct impact of external ambient temperature on the battery. Metal wires are installed inside insulating ceramic 18. When the battery leaks, the wires conduct the current to the inside of capacitor 17, and capacitor 17 is charged.

All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
